FU r102073:
* (bug 32367) Fixed SpecialMovePage to not call wfLocalFile() on a non file title and expect an actual File back. Previously "worked" due to an old file title checking loophole (File objects with non File: titles).
* Use File::normalizeTitle() in some more functions that were still doing their own incomplete normalization.
* Updated FileRepo::newFile() docs to reflect that it can return null; wfLocalFile() docs already mentioned this.
